Sonel MPI-502: Multifunction Electrical Installations Meter

Description

Short circuit loop parameters measurements:

• measurements of short circuit loop impedance in networks with rated voltage: 220/380 V, 230 V/400 V, 240/415 V and frequency 45…65 Hz,
• measurements of short circuit loop impedance with current 15 mA without tripping the circuit breaker.

Testing the RCD breakers of AC, A types:

• testing of prompt, short-delay (general) and selective RCDs for the rated current values 10, 30, 100, 300, 500 mA,
• IA measurement
• RE and UB measurement without tripping the circuit breaker,
• extended RCD test function AUTO, with measurement of Z_L-PE with current 15 mA – measurement of I_A and t_A during one RCD tripping.

Detection of the replacement L and N in the socket and automatic conversion in the meter.

Low voltage resistance measurements of protective circuits and junctions:

• measurement of resistance with ±200 mA current
• calibration of test leads – possibility of using any length of test leads,
• low current resistance measurement with accoustic signalling
